摘　　要：解决了基于动态周期事件触发切换控制策略的DC-DC变换器系统稳定性问题.事件触发机制可以在提升控制效果的同时节省通信资源.并且在事件触发机制中引入动态变量可以令事件触发条件基于系统的实际情况发生改变,提高了系统的稳定性和鲁棒性.经过对各种触发策略的比较分析,结果表明动态周期事件触发的切换控制方法能够在保证系统性能的前提下有效降低通信负担.最后,通过DC-DC升压变换器仿真实例说明了所建立结果的有效性.The stabilization of DC-DC converter system with a switching control approach based on dynamic periodic event-trig-gered mechanism is addressed in this study.The event-triggered mechanism saved the communication resources and improved the control performance.Meanwhile,by considering dynamic variable,the event-triggered condition could be changed depending on the actual situation of system,which improved the stability and robustness of the system.The comparison and analysis of vari-ous triggering strategies showed that the switching control method of dynamic periodic event-triggered mechanism could ensure that the system performance well and effectively reduced the communication burden.Finally,a simulation example of DC-DC boost converter was given to illustrate the effectiveness of the proposed control strategy.
